Abstract
Described herein are electrical applicator devices having a funnel-shaped portion with one or more electrodes on a distal-facing end region of the funnel shape. These devices may be deployable by inverting a braided or woven body back into itself to form the funnel. These devices may be used to perform a medical procedure, such as an ablation procedure.
Claims29
1-49. (canceled)
An electrical applicator device, the device comprising:
- a braided or woven body having a distal end and a proximal end;
- an inner deployment member extending within the braided or woven body and coupled to a distal attachment site of the braided or woven body, wherein the inner deployment member is configured to be movable to invert a distal end region of the braided or woven body to form a funnel shape having a distal-facing outer region;
- a first electrode formed at least partially around the distal-facing outer region of the inverted funnel shape;
- and
- a second electrode configured to contact tissue to be ablated and positioned at least partially within an opening of the funnel shape when the braided or woven body is inverted.
2 more elements
An electrical applicator device, the device comprising:
- a braided or woven body;
- a first region of the braided or woven body configured to form a first funnel shape, the first funnel shape having a first distal-facing outer region,
- a second region of the braided or woven body configured to form a second funnel shape, the second funnel shape having a second distal-facing outer region;
- a first electrode formed at least partially around the first distal-facing outer region;
- a second electrode formed at least partially around the second distal-facing outer region;
- and
- an inner deployment member extending within the braided or woven body and coupled to a distal end of the braided or woven body, wherein the inner deployment member is configured to be withdrawn proximally to invert the braided or woven body to form at least one of the first funnel shape and the second funnel shape, or both the first funnel shape and the second funnel shape.
4 more elements
An electrical applicator device, the device comprising:
- a braided or woven body having a lumen extending distally;
- an inner deployment member extending within the braided or woven body and coupled to a distal end of the braided or woven body, wherein the inner deployment member is configured to be withdrawn proximally to invert a distal end region of the braided or woven body into the lumen of the braided or woven body to form a first funnel shape having a first distal-facing outer region, wherein a second region of the braided or woven body is configured to invert into the lumen of the braided or woven body to form a second funnel shape that concentrically surrounds the first funnel shape and includes a second distal-facing outer region;
- a first electrode formed at least partially around the first distal-facing outer region;
- a second electrode formed at least partially around the second distal-facing outer region;
- and
- a third electrode distal to the distal end of the braided or woven body, wherein the third electrode is positioned at least partially within an opening of the second funnel shape.
